Vector performed an experiment at a local farm to determine if the addition of bananas to his biomass cow manure recipes helps produce more or less energy. He collected random samples of manure and bananas from the farm, prepared 15 bottles of each of both mixtures, and placed a balloon on top of each bottle. After two weeks he measured the circumference of each ballon in centimeters; the bigger the balloon grew, the more energy that was produced. The results of the experiment are displayed in the box plots below.
What can Vector report to his local Biogas Club about the results of his experiments?
Answers
Answer:
About 75% of the time, the mixture of cow manure and mashed bananas IS LIKELY to produce MORE biogas than pure cow manure on THIS local farm.
Iready 100%
Answer:
The range is more consistent with pure cow manure, but the mixture of cow manure and mashed bananas creates more biogas overall.

Answers
Answer:
1. Distributive Property
2. Subtraction Property of Equality
3. Addition Property of Equality
The property that justifies each step of 5(x-1) = 4x + 13 is 5x - 5 = 4x + 13.
What is distributive property ?Distributive property is when we distribute and multiply in between addition and subtraction
Given 5(x-1) = 4x + 3.
We know a(b+c) = ab + ac which is distributive property.
So, 5(x-1) = 4x + 3.
5x - 5 = 4x + 3.
Solving these problem and finding the value of x
5x - 5 = 4x + 13.
5x - 4x = 13 + 5.
x = 18.

Find the product of each expression using properties of complex numbers.
1. (x + 3i)(x − 3i)
2. (x − 4i)(x + 4i)
3. (x + 8i)(x − 8i)
Answers
Answer:
[tex](x+3\mathbf{i})(x-3\mathbf{i})=x^2+9[/tex]
[tex](x-4\mathbf{i})(x+4\mathbf{i})=x^2+16[/tex]
[tex](x+8\mathbf{i})(x-8\mathbf{i})=x^2+64[/tex]
Step-by-step explanation:
Complex Numbers
The complex numbers are known by having an 'imaginary' part along with the real part. They can be expressed like a + bi, where
[tex]\mathbf{i}=\sqrt{-1}[/tex]
Or, equivalently:
[tex]\mathbf{i}^2=-1[/tex]
Let's find the result of the following products. On each one of them, there is a sum of a binomial multiplied by the subtraction of a binomial with the very same terms. It leads to a well-known polynomial identity:
[tex](a+b)(a-b)=a^2-b^2[/tex]
1. [tex](x+3\mathbf{i})(x-3\mathbf{i})[/tex]
Applying the above-mentioned identity:
[tex](x+3\mathbf{i})(x-3\mathbf{i})=(x^2-(3\mathbf{i})^2)[/tex]
[tex]=x^2-9\mathbf{i}^2[/tex]
Since [tex]\mathbf{i}^2=-1[/tex]
[tex](x+3\mathbf{i})(x-3\mathbf{i})=x^2-9(-1)[/tex]
[tex]=x^2+9[/tex]
2. [tex](x-4\mathbf{i})(x+4\mathbf{i})[/tex]
Proceed in the same way as before:
[tex](x-4\mathbf{i})(x+4\mathbf{i})=(x^2-16\mathbf{i}^2)[/tex]
[tex]=(x^2-16(-1))[/tex]
[tex]=x^2+16[/tex]
3. [tex](x+8\mathbf{i})(x-8\mathbf{i})[/tex]
[tex](x+8\mathbf{i})(x-8\mathbf{i})=(x^2-64\mathbf{i}^2)[/tex]
[tex]=(x^2-64(-1))[/tex]
[tex]=x^2+64[/tex]

Three families bought food at the baseball game. The Smith family spent $16.50 on 3 hot dogs, 2 sodas, and 1 candy bar. The Patterson family spent $26 on 4 hot dogs, 4 sodas, and 2 candy bars. The Nguyen family spent $13.75 on 2 hot dogs, 1 soda, and 3 candy bars. Which of the following systems of equations could be used to determine the price of each item?
Answers
Answer:
Step-by-step explanation:
Let
Price of
Hotdogs = x
Sodas = y
Candy bar = z
Smith family
Hotdogs = 3
Sodas = 2
Candy bar = 1
Total cost = $16.50
3x + 2y + z = 16.50
Patterson family
Hotdogs = 4
Sodas = 4
Candy bar = 2
Total = $26
4x + 4y + 2z = 26
Nguyen family
Hotdogs = 2
Sodas = 1
Candy bar = 3
Total cost = $13.75
2x + y + 3z = 13.75
The equations
3x + 2y + z = 16.50 (1)
4x + 4y + 2z = 26 (2)
2x + y + 3z = 13.75 (3)
Multiply (1) by -2
-2(3x + 2y + z = 16.50)
-6x - 4y - 2z = -33
-6x - 4y - 2z = -33 (1a)
4x + 4y + 2z = 26 (2)
Add (1a) and (2)
-6x + 4x = -33 + 26
- 2x = -7
x = -7/-2
= 3.5
x = $3.5
Multiply (3) by -4
-4(2x + y + 3z = 13.75) (3)
-8x - 4y - 12z = -55 (3a)
Add (3a) and (2)
-8x - 4y - 12z = -55 (3a)
4x + 4y + 2z = 26 (2)
-8x + 4x -12z + 2z = -55 + 36
-4x - 10z = -29
Substitute the value of x into
-4x - 10z = -29
-4(3.5) - 10z = -29
-14 - 10z = -29
-10z = -29 + 14
-10z = - 15
z = -15 / - 10
= 1.5
z = $1.5
Substitute values of x and z into (1)
3x + 2y + z = 16.50
3(3.5) + 2y + 1.5 = 16.50
10.5 + 2y + 1.5 = 16.50
12 + 2y = 16.50
2y = 16.50 - 12
2y = 4.50
y = 4.50 / 2
y = $2.25
You are a screenwriter who is writing a script for an hour-long police drama. You have written 20 1/2 pages for act 1 and 5 1/2 pages for act 2.
How many pages have you written in total?
Answers
Answer:
You have written 26 pages in total.
Step-by-step explanation:
I always enjoyed adding fractions. Something about it is so... simple.
The problem is basically asking us to add 20 1/2 and 5 1/2 together.
I would first suggest adding both halves together, to make 1.
That way, we're left with 20 + 5 + 1. That seem easier, doesn't it?
Then we would add 20, 5 and 1 together, to get 26 whole pages.
And that, to an extent, is how I did it.
Hope this helps! :D
Answer:
Given:
Written pages for Act 1 = 20 1/2
Written pages for Act 2 = 5 1/2
For making mixed numbers like this easier to add, let's convert them first into an irrational number with this formula,
((Whole Number × Denominator) + Numerator)/Denominator
Thus,
for 20 1/2
((20 × 2) + 1)/2 = 41/2
for 5 1/2
((5 × 2) + 1)/2 = 11/2
Then we add,
41/2 + 11/2
Since, they have the same denominator, no more conversions need, proceed adding the numerators,
(41 + 11)/2 = 52/2 = 26
You've written 26 pages in total.

Answers
Answer:
they are the same thing
Step-by-step explanation:
Answer:
They are practically the same thing but if you want to get technical then they are related because A slope a measure of steepness. A line with a large slope, such as 25, is very steep. A line with a small slope, such as 1 /10 is very flat. So this means it will rise over run if that makes sense.

The area of a square garden is approximately 125 square feet. To the nearest foot, what is the length of the garden? Explain how you know in the work space provided.
Answers
Answer:
Length = 11.2 ft
Step-by-step explanation:
Area of a square garden = 125 square feet
Formula to find
Area of a square = length^2
Substitute the value of the Area of the square garden
Area of a square = length^2
125 = length^2
Find the square root of both sides
√125 = √length^2
11.18 = length
Approximately

How much is the number 727731000 in percent form
I need yall to answer this question quickly you will recieve a ton of points if you do.
Answers
Answer:
72773100000%
Step-by-step explanation:
"Percent" means "per 100" or "over 100". So, to convert 727731000 to percent we rewrite 727731000 in terms of "per 100" or over 100.
Multiply 727731000 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.
7277310001×100100=72773100000100
72773100000/100 is 72773100000 over 100 and means 72773100000 per 100. 72773100000 "per 100" means 72773100000 "percent" or 72773100000%
Therefore, we have shown that
727731000 = 72773100000%
Simplified Conversion:
Multiply by 100 and add the percent sign %
727731000 × 100 becomes 72773100000%
Shortcut Conversion:
Move the decimal point 2 places to the right and add the percent sign %
727731000 becomes 72773100000%
